Stress and Exercise [PDF]

, 2007
Age-related immunological and endocrinological changes may have implications for resilience to stress in older adults. We hypothesise that the combination of adrenopause and immunesenescence may leave this population particularly vulnerable to the ...

An effective stress equation for unsaturated silt considering the microstructure of pore water and its verification

Shuiwen dizhi gongcheng dizhi, 2022
Accurate determination of the effective stress coefficient is an important thing in the study of the effective stress of unsaturated soils. However, the existing effective stress coefficients have not well considered the effect of the microscopic ...

Anisotropic Local Stress and Particle Hopping in a Deeply Supercooled Liquid [PDF]

, 2002
The origin of the microscopic motions that lead to stress relaxation in deeply supercooled liquid remains unclear. We show that in such a liquid the stress relaxation is locally anisotropic which can serve as the driving force for the hopping of the ...

Effective behavior of nematic elastomer membranes [PDF]

, 2015
We derive the effective energy density of thin membranes of liquid crystal elastomers as the Gamma-limit of a widely used bulk model. These membranes can display fine-scale features both due to wrinkling that one expects in thin elastic membranes and due

Experimental study on stress sensitivity of high‐temperature and high‐pressure sandstone gas reservoirs in Yingqiong Basin

Energy Science & Engineering, 2020
Performing stress‐sensitivity evaluation on a high‐temperature and high‐pressure gas reservoir is essential for correctly understanding the characteristics of physical property changes and reasonably designing the development scheme of a reservoir under ...

Long-range, critical-point dynamics in oil field flow rate data [PDF]

, 2006
Earthquake triggering data exhibit long-range spatio-temporal correlations of the power-law form C(l) ∼ l−α and anomalously-slow temporal diffusion of the mean triggering distance of the form: 〈l〉 ∼ tH, with H < 0.5.

Analytical model for undrained residual shear strength of foam-conditioned coarse-grained soils in large deformation based on effective stress principle

Yantu gongcheng xuebao, 2023
Foam is usually used in soil conditioning of earth pressure balance shield tunnelling. The smooth muck discharge and chamber pressure transmission require foam-conditioned coarse-grained soils with suitable flowability to avoid face instability and ...

Influence of imipramine on the duration of immobility in chronic forced-swim-stressed rats. [PDF]

, 2004
We studied the influence of imipramine on the duration of immobility in chronic forced-swim-stressed rats. Both single and chronic administration of imipramine potently shortened immobility in naive rats during forced-swim testing.

Experimental study on effective stress sensitivity of coal permeability based on dynamic drainage process

Meitan kexue jishu
The dynamic changes in reservoir permeability during coalbed methane well drainage largely depend on variations in effective stress and pore structure.

Elastocaloric response of PbTiO3 predicted from a first-principles effective Hamiltonian [PDF]

, 2015
A first-principles based effective Hamiltonian is used within a molecular dynamics simulation to study the elastocaloric effect in PbTiO3. It is found that the transition temperature is a linear function of uniaxial tensile stress.
